Improvement in clutches for machinery



Letters Patent No. 109,450, dated November 22, 1870.

VIMPROVEMENT IN CLUTCHES FOR MACHINERY.

The' Schedule referred to in these Letters Patent and making part of thesame.

We, JOHN E. lLUMMnn and J'osnru l. Noves, of Binghamton, in the countyof Broome, and State of New York, have invented certain ImprovementsinClutch for legging-Maehincs, of which the following is a specification.

Our invention relates to the combination, arrange ment and applicationof a. clutch and switch forconnecting and disconnecting the fly-wheel orpulley from tbc main shaft ofthe ordinary pcgging-machine, in such amanner that said ly-whecl or pulley may be made to work loosely on theshaft, or be connected with it and -give motion tothe operating parts ofthe. machine, whereby the machine may be instantly stopped and put inmotion again at any desired point ofthe work. Figure 1 in theaccompanying drawing is a view of the y-wheel or pulley connected,embodying our invention.

Figure 2 shows the clutch disconnected, and secured in the detcnt of theswitch.

Figure 3 is the clutch and shaft detached. Figure 4 lshows the fly-wheelor pulley and annular notched iiange, with a section of the shaft.

Figure 5 is aJ section of the switch, showing the disengaging-ngel'l anddetent to hold the clutch. A is 'thc drivingpulley or fly-wheel, whichis hung loosely on the main shaft 15. On the inside of this pulley is aprojecting annular flange C, with notches o (t for. the reception of theclutch 1), which vis hinged to the main shaft B, and made to enter saidnotches by the pressure of a spiral spring working in a transverse holein the shaft upon a projection, l), on vthe clutch 1) as shown in iig.3. rl`hc notches a a in the flange C have a full hea-ring on theirworking sides, and a partial bearing or shoulder on the other side, toprevent the hack-lash of the clutch occasioned by the alternatewlift-ing and dropping of the peg-driver.

, On this side the edges c c are tapered down to allow the clutch I) topass freely into the notch a..

E is the switch, which is operated by the handle F. This switch isbentto correspond with the circular form of Athe .Ilange C, and has aprojecting finger,A e, which, when brought in contact with the face ofthe flange C, engages with the projecting end of the clutch 1), andbythe momentum of the fly-wheel throwsit into t-he dctent j, in whichpositionit is shown in g. 2.

In using our invention, the pulley or ily-wheel A being loose or'disconnected with the shaft B,'is rst pnt in motion at a speed of aboutfour hundred revolutions per minute. flihe handle F of the switch isthen depressed, which disengagcs the clutch D from the detcnt fwhicl1clutch slides into the notch a, as before described, thereby connectingthe yhwhcel or pulley A with the main shaft, and giving motion to themachine.

The 'machine is stopped by raising the handle, which engages the finger'c of the. Vswitch with the clutch D, and throws it into the detent, asdescribed,

whereby-the operation of pegging may be instantly suspended at anydesired position ofthe work, leaving ,no awl-holes unfilled in thespace, accomplishing more work in' a given time with better results, andwith less wear and deraugcm'ent ot' the machine than by theordinarymethod.

XVe claim as our invention-` The combination and arrangement ot' clutchD and switch E, handle F and dctent f, with the annular notched flangeC, iiy-whecl or pulley A, spring o and shaft B, all being constructedand operating as hercinbcfore set fort-h.
